Landscapes are shaped by geomorphic processes, but life also shapes landscapes. Interactions and feedbacks between organisms, ecosystems and geomorphic processes structure many dynamic environments, including rivers, coasts, hillslopes, aeolian and deglaciating landscapes. Yet, many biogeomorphic feedbacks remain poorly understood and quantified, in particular their mechanisms, strength and thresholds. As these landscapes are increasingly affected by climate and land-use change, understanding how biota influence geomorphic processes—and vice versa—is becoming increasingly important. Improved understanding can support nature-based solutions (NbS) and geoheritage conservation and contribute to the conservation of geodiversity and biodiversity, as well as the maintenance of ecosystem functions and services.

Our session brings together research on interactions between plants, animals, ecosystem processes and geomorphic processes, landforms and materials. We particularly seek to connect researchers working in environment-specific communities, including fluvial, coastal, aeolian and hillslope geomorphology, and provide a forum to explore common biogeomorphic processes and feedbacks across environments. We welcome research spanning functional traits and individual organisms to ecosystems and landscapes, from mountain environments to the sea. By bringing together studies from different environmental settings, we aim to identify common principles, context-dependent contrasts and transferable insights in biogeomorphology, and foster synergies between research communities.

Topics may include, but are not limited to:
• biogeomorphic processes, rates and feedbacks;
• the role of plant and other organisms’ traits in geomorphic processes;
• biota as ecosystem engineers, landform creators and landscape shapers;
• biogeomorphic feedbacks under climate and land-use change;
• applications of biogeomorphology for nature-based solutions, hazard mitigation and geoheritage conservation

Innovative approaches—including field monitoring, laboratory and flume experiments, remote sensing, artificial intelligence, numerical and statistical modelling, and combinations thereof—are warmly welcomed, especially when providing new insights into interactions between life and landscape, resolving previously inaccessible interactions or pushing scalar boundaries.
